How to use ISO8601 date format in Tableau Desktop 2019.3

Tableau 2019.3 lets you lock every date to the ISO 8601 standard in a couple of clicks.

Part ofWhat's new in Tableau 2019.3
  • Tableau Desktop 2019.3 added the ability to set the default date format to the ISO 8601 standard, which enforces a consistent date format to avoid confusion
  • To apply it, right-click your data source, go to Date Properties, and select ISO 8601 under the default calendar option
  • Once ISO 8601 is selected the other date controls are greyed out because the standard already specifies a fixed format
